Established in July, Showa 32 (1957).Sources

Established in July, Showa 32 (1957). Operating mainly in Utsunomiya and Kanuma, with a business area covering Tochigi Prefecture, focusing on housing, construction, and real estate sales brokerage. The company is highly regarded for its detailed responses during construction, starting with ground investigation, and continuous after-sales follow-up, resulting in a high proportion of customers through referrals. With the concept of "Living in Tochigi, where the wind blows sweetly," the company has built a trusting relationship with customers over more than 50 years since its founding, and its know-how of Tochigi's climate, natural features, and environment is embedded throughout, embodying "homes that only Kakunishi can create."Sources
